Foreword
Service-Oriented Computing (SOC) is the computing paradigm that utilizes soft-
ware services as fundamental elements for developing and deploying distributed
software applications. Services are self-describing, platform-agnostic computa-
tional elements that support rapid, low-cost composition of distributed applica-
tions. They perform functions, which can be anything from simple requests to
complicated business processes. Services allow organizationstoexpose their core
competencies programmatically via a self-describing interface based on open
standards over the Internet (or intranet) using standard (XML-based) languages
and protocols. Because services provide a uniform and ubiquitous information
distributor for wide range of computing devices (such as handheld computers,
PDAs, cellular telephones, or appliances) and software platforms (e.g., UNIX or
Windows), they constitute a major transition in distributed computing.
A Web service is a specific kind of service that is identified by a URI that
exposes its features programmatically over the Internet using standard Internet
languages and protocols, and can be implemented via a self-describing interface
based on open Internet standards (e.g., XML interfaces which are published in
network-based repositories).
Understanding the conceptual underpinnings and mastering the technical
intricacies of Web services is anything but trivial and is absolutely necessary to
construct a well-functioning service-based system or application. Web service
technology is undergoing continuous, rapid evolution, thanks to both standardi-
zation efforts pushed forward by industry and the research efforts of the scientific
community.
Web services standards are still evolving. However, they seem to converge
today on a handful of standards: the Simple Object Access Protocol (SOAP) for
service communication, Web Services Description Language (WSDL) for service
description, Universal Description, Discovery, and Integration Infrastructure
(UDDI) for registering and discovering services, and the Business Process Exe-
cution Language (BPEL) for service composition. A plethora of WS-* specifica-
tionsalsoexiststodescribe the fullspectrumofactivities related toWebservices
in topics such as reliable messaging, security, privacy, policies, event processing,
and coordination, to name but a few.

viii Foreword
Leading international conferences, such as the International Conference on
Service-Oriented Computing (ICSOC), the International Conference on Web
Services (ICWS),the International Conference onService Computing(SCC),and
others, have spearheaded groundbreaking research efforts. This has led to the
emergenceofnoveltopicssuchassemanticWebservices,automatedWebservice
composition, Web service recommendations, quality of service, trust, and a range
of other interesting themes. Related conference series such as Web Engineering,
Cloud Computing, Business Process Management, HCI, and Database related
conferences, have all been strongly influenced by the emergence of Web services
andconsistentlyfeatureWebservicerelatedtopicsintheircallsforpapers.These
conferences contribute to the wealth of knowledge that is growing exponentially
around Web services.
The content of this book and that of its companion book Advanced Web Ser-
vices (Springer,2013) reflect suchactivities. Itisatestimonialoftheleading role
of its editors and their highly influential work in the area of Web services.
Together, both books cover an enormous wealth of important topics and tech-
nologies that mirror the evolution of Web services. They provide an exhaustive
overview of the challenges and solutions of all major achievements pertaining to
Web services. Each chapter is an authoritative piece of work that synthesizes all
pertinent literature and highlights important accomplishments and advances in its
subject matter.
To my knowledge, this is the first attempt of its kind, providing complete
coverage of the key subjects in Web services. I am not aware of any other book

will serve to unify, advance, and challenge the scientific community in many
important ways.
It is a real pleasure to have been asked to provide the foreword for this book
collection. I am happy to commend the editors and authors on their accomplish-
ment, and to inform the readers that they are looking at a landmark in the

Preface
Web Service technology is undeniably the preferred delivery method for the
Service-Oriented Computing(SOC)paradigm. Ithas evolved overthe yearstobe
a comprehensive, interdisciplinary approach to modern software development.
Webserviceshavegonebeyondsoftwarecomponentizationtechnologytoembody
andexpressthesoftwaremanifestationofageneraltrendtransformingourmodern
society from an industrial, production-centric economy into a digital, service-
centric economy. Web services aim to provide the missing conceptual links that
unify a variety of different disciplines, such as networking, distributed systems,
cloud computing, autonomic computing, data and knowledge management,
knowledge-based systems, and business process management. Web services are
the technological proxies of services that power much of the developed and
increasingly developing economies. In this respect, Web services play a central
role in enabling and sustaining the growth of service-centric economies and help
modernizing organizations, companies and institutions also from an IT
perspective.
Overthelastdecade,Webserviceshavebecomeathrivingareaofresearchand
academic endeavors. Yet, despite a substantial body of research and scientific
publications,theWebservicescommunityhasbeenhithertomissingaonestop-shop

aseriousattempttofillthisgapandserveasaprimarypointofreferencereflecting
thepervasivenatureofWebservices.
This book is the first installment of a two-book collection (we discuss the
advanced topics in the second book, Advanced Web Services, Springer, 2013).
Together, they comprise approximately 1,400 pages covering state-of-the-art
theoretical and practical aspects as well as experience using and deploying Web
services. The collection offers a comprehensive overview of the scientific and
technicalprogressinWebservicestechnologies,design,architectures,applications,
and performance. Thefirst book of the collectionconsists oftwo major parts:

x Preface
I Foundations of Web Services (12 chapters)—It explores the most representa-
tivetheoreticalandpractical approachestoWebservices,withaspecial focus
on the general state-of-the-art approaches to Web service composition;
II ServiceSelectionandAssistedComposition(16chapters)—Itfocusesonother
aspectsofWebservice compositionproblem,specificallytakesadeep lookat
non-functional aspects (e.g., quality of service), Web service recommenda-
tions, and how Web service composition is made easy for less expert
developers.
The second book (Advanced Web Services, Springer, 2013) consists of three
major parts:
I Advanced Services Engineering and Management (11 chapters)—It explores
advanced engineering problems, such as Web service transactions and recov-
ery, security and identity management, trust and contracts, and Web service
evolution and management;
II Web Service Applications and Case Studies (5 chapters)—It covers concrete
scenarios of the use of Web service technology and reports on empirical
studies of real-world Web service ecosystems;
III Novel Perspectives and Future Directions (10 chapters)—It surveys approa-
ches of the applications on how the Web service paradigm can be applied to
novel contexts, such as human-centric computing, human work and the
Internet of Things, and discusses the value of Web services in the context of
mobile and cloud computing.
The topics covered in the collection are reflective of their intent: they aim to
become the primary source for all pertinent information regarding Web service
technologies, research, deployment and future directions. The purpose of the two
books is to serve as a trusted and valuable reference point to researchers and
educators who are working in the area of Web services, to students who wish to
learnaboutthisimportantresearchanddevelopmentarea,andtopractitionerswho
are using Web services and the service paradigm daily in their software devel-
opment projects.
This collection is the result of an enormous community effort, and their pro-
duction involved more than 100 authors, consisting of the worlds leading experts

undergone a rigorous review process, involving three independent experts in two
rounds of review. We are also very grateful to Springer for their continuous help
and assistance.
